Abstract

A power steering apparatus (11) includes a motor, a torque sensor (22), and a motor resolver. The motor generates an assisting force to reduce the steering force of the steering wheel. The torque sensor (22) detects the steering torque of the steering wheel. The motor resolver detects the rotational angle of the motor. An electronic control unit (ECU) detects the absolute position of the steering wheel based on a detection signal (Rt) sent from a second resolver (24) of the torque sensor (22) and a detection signal (Rm) sent from a motor resolver. As a result, the cost is reduced and the absolute position of the steering wheel is accurately detected.
